ON MY OTHER CAR 1996 FORD CONTOUR THE HEATER/AC FAN DOES NOT WORK, WHAT MIGHT BE THE PROBLEM

If you can verify you have power and ground to the fan, then the fan motor is bad and needs to be replaced. If you have no power to the fan motor, check the fuses. Also, make sure you don't have high speed on your fan only, this would indicate your resister pack is bad. Let me know what you find.

Welcome to 10w40.com. Check your for fuses interior of vehicle the 30A is to your blower motor fuse may not be getting any power. Check your wiring in fuse box under the hood for possible shorts or defectiveness.
Check for voltage to the blower motor fuse, # 37, in the interior fuse box with the blower switch turned to any speed. If no voltage is present, test the 60A maxi fuse, # 3, in the underhood fuse box for voltage and make sure it is not blown. NOTE: This may be an 80A fuse if the vehicle is equipped with MEC III ABS. If OK, raise the fuse box and check for corrosion on the Red wire on the output side of fuse 3. If no voltage is present, the problem is likely an open circuit in the underhood fuse box. For harness concerns like cracking or shrinking insulation, Ford has issued a program, 99M03 where they will replace, free of charge, faulty underhood harnesses for 10 years/100,000 miles. Good luck.

thank you Sam Clem, it was the number 3 fuse, i almost bought the heater fan fuse which was $20.00, then i would have bought the fan motor, never thought it could be the number 3 abs system fuse as it read in the manual. you saved me some money and aggrevation.
